Hello, I run a Monero mining pool using MiningCore with a custom UI. I’d like to know if there will be any updates for this software following the introduction of RandomX v2, or if I should start looking for an alternative. I’m aware that it’s not exactly the newest software, but it still gets the job done. Could you provide more information on this?

Does Proof of Capacity (PoC) for Monero? Can I mine Monero with a HDD? If not what are some good trusted alternatives?

wrong miner tx in block: <fb877ea3400f731c2b948e87655368f1c0486e3c114bb3f8f3839bec1b2f9596>, b.miner_tx.vin.size() != 1

This error message appeared while solo mining Monero; does it mean the block was rejected?

Is it just me or is the website totally down?

I need help , I have few computers running nano pool, suddenly one of the computer displays this messages constantly.

All other computers working fine with same settings.

any help would be appreciated.

I wanted to know whether mining on an Apple Silicon Mac is worth anything, so I built a free, open-source app that benchmarks the CPU and GPU and works out profit after electricity using the Mac's own power sensor. Here's my M5 Max (18-core CPU, 40-core GPU) at my $0.17/kWh:

| Engine | Coin | Hashrate | Net per day |

|---|---|---|---|

| XMRig (CPU) | XMR | 8.4–8.5 kH/s | −$0.01 to −$0.07 |

| kawpow-metal (GPU) | RVN | 47.8 MH/s | −$0.24 |

| ethminer-m1 (GPU) | ETHW | 40.3 MH/s | −$0.30 |

| UselethMiner (CPU+GPU) | ETHW | 43.7 MH/s | −$0.35 |

Live run, Monero on the CPU (screenshot below): 8.4 kH/s at 96 W above idle, $0.33/day gross against $0.39/day of electricity, so −$0.07/day. Break-even works out to about $0.14/kWh. Chip sat around 155 °F with no thermal throttling.

Takeaways:

- On cheap power (under ~$0.14/kWh) or solar, XMR on the CPU makes a small profit. At typical US rates it costs you a few cents a day.

- The GPU loses money on every coin it can mine.

- RandomX at ~8.5 kH/s for ~90–96 W is decent efficiency, but it doesn't beat electricity at $0.17.

What the app does (MacDualMiner, GPL-3.0):

- XMRig on the CPU, Metal/OpenCL miners on the GPU, together or separately

- Ranks every mineable coin by net USD/day from your own benchmark and tells you when a chip would lose money (it still lets you mine if you want)

- Can pay Monero mining out in DOGE/LTC/BTC etc. via unMineable, handy for Trust Wallet

- Shows your pool balance (SupportXMR, Kryptex, unMineable, 2Miners)

Not notarized by Apple yet, so macOS asks you to approve it on first launch (the README explains how).

Disclosure: I made it. Free, no fees beyond the miners' and pools' own. If you have an M1–M4, I'd love your hashrates (Help › Share Your Hashrate in the app).

We have al seen how XMR is on fire this year, with a price increase of something between 50 and 100% (depending on when you measure it).

Now I have also been looking at the hashrate chart, which seems to be somewhat stable.

I am wondering, shouldn't the hashrate increase along with price? How long it takes on average for new mining systems to come online?

Is mining now cheaper (or more profitable) relatively speaking compared to a year ago?

Bought an Orange Pi 4 Pro, flashed Armbian (CLI), then built & ran XMRig rx/0 benchmark just for fun. And here's my test result:

My Orange Pi 4 Pro (6GB) consumes 1.9W when not mining (w/ Wi-Fi connected + micro SD card). I can get higher efficiency (62.7 H/s/W) with 2x A76 only with less hash rate.

It's interesting to see that using all cores did not get best hash rate on RandomX. I suspect: it hits memory bandwidth limit (I don't see any sign of dual channel DDR on board) or TDP limit.

And... I did this test this just for fun. SBCs are good for low-power Monero nodes, but not so good for Monero mining (at least in terms of raw hashrate and H/s/W).

Anyone here try Pearl mining on 9070xt? Im looking for tips, miner,pool,power settings.

MacDualMiner is a free, MIT-licensed macOS app that wraps the official XMRig release for Apple Silicon (M1–M5). It handles the config, shows live hashrate, shares and net USD per day using the Mac's power sensor, and can switch between RandomX coins (XMR, ZEPH, QRL, ETI, EPIC) based on WhatToMine data.

On an M5 Max, XMRig does about 7.6–7.9 kH/s with all 18 cores, which comes out at roughly +$0.08/day net at $0.17/kWh.

Hello

I have installed the last version of monerod and also p2pool

I have a 13 CPU Ryzen 7950x

From the mini pool I have this now

If you look at the Reward lots of paiement last day then nothing

From the Monerod log I had 22 block behind..... No problem of tilme

So question :

Since I got lots xmr last day more than the prediction so the system is adapting.... Or pénaliser ......

Any ideas , comments ?

Hey guys I need some help.

Currently I have 10 rigs 3900x with hive os mining in full at 124kh/s and 1320w/h. For me that’s pretty fine. I let it run to monero ocean and it’s ok.

But I like to get away from hive os.

I think it’s better to get Linux LTS without GUI. Than fine tune the settings without BIOS for the same results. Next point them all to my own pool or xmrrig proxy and than point the proxy or pool to my own node on my raspberry running umbrel os.

Is that possible and does it make sense? I really need some help about that.

Thanks in advance

Hey everyone,

I’m planning to invest around €10,000 in Monero mining hardware. I’d like to buy from a reputable EU-based provider with proper warranty, VAT/invoice, and support, not a random marketplace listing...

What would you recommend today: several high-end CPU rigs (Ryzen 9 / EPYC), a RandomX ASIC such as the Antminer X9, or a mix? ... I'm a bit lost in what I should buy as best investment overall.

If you’ve bought recently in the EU, which vendor and hardware would you choose with this budget?

Thanks!

I'm trying to find out whether the Pinecone R1X RandomX ASIC miner actually exists as working hardware.

Has anyone here:

• Seen a real R1X unit in person?
• Received one from a seller?
• Seen independent photos, videos, or actual mining results from a working unit?

I'm not looking for product listings, promotional images, or manufacturer specifications. I'm specifically interested in independent evidence that the hardware exists and works.

Any firsthand information would be appreciated. Thanks!

This post suggests that the EPYC 7742 would suffer a 30% drop in hashrate on RandomX V2

https://np.reddit.com/r/AskMonero/comments/1sy55h6/is_randomx_v2_nerfing_highend_cpus_my_recent/

The benchmarks here suggest that the Zen 2 architecture's hashrate would decrease roughly 85%

CPU, power (W), v1 (H/s), v2 (H/s), decrease

Ryzen 9 3900X, 70.62, 12197, 10765, 88.3%
Ryzen 9 3900X, 67.98, 12259, 10233, 83.5%
Ryzen 9 3700X, 88, 8624, 7361, 85.4%

https://gist.github.com/SChernykh/6058ecf01c929883b9d19c7eeadc8809

However, the Zen 5 (9950x) and very oddly Zen 1 (Ryzen 7 1700X) does not seem to have a drop at all.

Does anyone know how exactly would the AMD EPYC 7k62 suffer on RandomX V2?

Why is the Zen 2 architecture (but not the Zen 1) hit especially hard by RandomX V2?

Well i work in a place where i see 10-30 usbs everyday amd i stumbled across this very interesting piece of script that i want to understand.

What it does is basically it masks the folder of any input usb and puts it into a shortcut that if you wish to access you need to give it admin privileges upon that it runs a background process of implementing a hidden minner in your system 32 file and it does this with every usb you stick on that pc and on and on
Can anyone refer me to a place to learn more about the source code of it or a repo that explains the workflow of that and which tools are used against this kind of attacks

This was a huge problem for me as the situation took long and i need to understand what is actually this kind of app/script
it does as following :

1) you pug a USB drive for the first time, it runs normally.

2) the second time you pug it in you see inside that usb a (Shortcut) with the same name of the usb you plugged in.

3) when you click it to access the files that you have on you usb it asks for AD.

4) then it runs scripts that takes a hidden XMR minner all the ways to the System32 folder of you PC as: C:Windows/system/wsvsc or wscvv

5)the minner is suspended when you open apps like task manager or monitor apps or even using ore that 70% of the cpu or hitting + 90'

what i really want to know is how is that possible and if someone has a repo or a source code that i can learn and see how they could write scripts like this so i can know more how to defend against it and thanks <3

so i know there are a lot of videos of how to mine xmr but its all so confusing i want to use mini p2p pool to mine but i dont know how to set it up can yall please help me out thanks

We just released HiveOS and mmpOS packages for parnianminer, the CPU miner for ParnianCoin (PARC), a PascalCoin fork using RandomHash2.

Like RandomX, RandomHash2 is designed to be CPU-friendly and ASIC-resistant, so if you already run CPU rigs it's an easy coin to test.

- Custom miner, no packages to install (portable Linux x64)

- Picks the pool port by hashrate automatically, with a backup pool

- Hashrate and shares show up in the dashboard

Guide + downloads:

https://github.com/ParnianCoin/parniancoin-miner/releases/tag/v2.4.1-rigs

It's a small project growing organically. Disclosure: I'm part of the team. If you have spare CPU on your rigs, we'd love feedback, especially on hashrate numbers for different CPUs.

The mini version of p2pool has been down for over 24 hours. https://mini.p2pool.observer/miners

Does anyone know if this is still maintained? Will mining still work?

OK I'm new to Monero Mining, for now just using Monero Wallet and my sync'd local node to mine Monero on Ubuntu 24.04.

Have received a couple shares so have a little in my wallet. Initially on the observer - https://mini.p2pool.observer/ - I saw the shares along with a notice that I needed to update my p2pool from 4.17.1 to 4.18.1, which I did.

Now for the last 36 hours when I check the P2Pool Mini Observer it says no shares for this wallet. The wallet address is correct. I got the shares from Mini P2Pool. I don't understand why it no longer knows about the shares it sent me. Anyone else having this issue?

I wanted to join the Raffle on the Observer but now with no shares showing I of course can't join it.

Anyone know if there's a way to contact the Observer admins via reddit?

Thx All.

What operating system are you using to mine monero (xmr) ?

at what point does it become worth it to pay for hive os?

Is anyone running a lot of rigs and not using hive os? what os do you use if you want to mine a lot but don't want to pay for hive os?

Starting with $25k-$30k to put into equipment. Electricity is too expensive where i live (Northeast USA). DM if interested we can discuss! Open to joining an existing farm as well!
